The hybrid toxins are produced by a novel combination of the different domains of such a protein by adopting recombination technology. The known partially deficient toxin is CrylAb, in which a part of amino acid sequence is deficient. In the modified toxins, one or a plurality of amino acids of a natural toxin is/are replaced.

Examples of such toxins and genetically modified plants capable of synthesizing such toxins are described in EP-A-0 374 753, WO 93/07278, WO 95/34656, EP-A-0 427 529, EP-A-451 878, WO 03/052073, etc.

The toxins contained in such genetically modified plants impart resistance to insect pests of Coleoptera, insect pests of Hemipteria, insect pests of Diptera, insect pests of Lepidoptera and Nematoda to the plants. The agrihorticultural insecticide of the present invention can also be used in combination with or by systematization with such technique.

For control of various pests, the agrohorticultural insecticide of the present invention need only be applied to the plant expected to allow occurrence of pests and nematode, as it is or after being properly diluted with or suspended in water or the like, in an amount effective for control of the pests or nematode. For example, for pests and nematodes that occur in fruit trees, cereals, vegetables and the like, the insecticide is sprayed on the stem and leaf parts, or absorbed from the root by seed treatments such as dipping the seeds in a drug, dressing of seeds, Calper treatment and the like, soil treatment such as soil whole layer blending, planting row application, bed soil blending, cell seedling treatment, planting hole treatment, plant foot treatment, top dress, box treatment of rice, water surface application etc., and the like. In addition, the agrohorticultural insecticide can also be used by application to a culture fluid for culture fluid (hydroponic) culture, application by smoking or tree stem injection and the like.

The agrohorticultural insecticide of the present invention need only be applied to the place expected to allow development of pests, as it is or after being properly diluted with or suspended in water or the like, in an amount effective for control of the pests. For example, spraying on grain-storage insects, house pests, hygiene pests, forest pests and the like, as well as application, smoking, bait to house and architectural materials and the like can also be employed for use.

As methods for seed treatment, conventional methods such as a method comprising penetration of the agent by dipping of seeds in the liquid agent obtained by diluting or not a liquid formulation or a solid formulation, a method comprising adhering a solid formulation or liquid formulation to the seed surface by admixing the formulation with seeds, dressing and the like, a method comprising admixing the formulation with adhesive carriers such as resin, polymer and the like and forming a coat on the seeds, a method comprising application near the seeds simultaneously with planting and the like can be mentioned.

The “seed” to be subjected to the seed treatment means a plant body in an early stage of growth, which is used for propagation, and includes seeds, as well as bulb, tuber, seed tuber, germ, propagule, scaly bulb, a plant body for vegetative propagation by cutting propagation, and the like.

The “soil” and “cultivation carrier” for plant when practicing the method of use of the present invention mean supports for cultivation of plants, particularly supports for growing roots, and the material is not particularly limited. The material may be any as long as plants can grow therein and specific materials include, for example, soils, nursery mat, water and the like. As a specific material, sand, pumice, vermiculite, diatomaceous earth, agar, gelled substance, polymer substance, rock wool, glass wool, wood chip, bark and the like can also be used.

As a method of application to crop plant stem and leaves, or grain-storage insect, house pest, hygiene pest or forest pest, a method including appropriately diluting a liquid formulation such as emulsion, flowable formulation and the like or a solid formulation such as a wettable powder or water dispersible granule and the like with water and spraying same, a method of spraying a dust, or smoking and the like can be mentioned.

For application to the soil, for example, a method comprising application of a liquid formulation to the plant foot of plant body, nursery for raising seedling and the like with or without dilution in water, a method comprising application of granules to the plant foot of plant body or nursery for raising seedling, a method comprising application of dust, wettable powder, water dispersible granule, granule and the like before sowing or transplantation to allow them to be incorporated into the entire soil, a method comprising application planting pit, planting row and the like with dust, wettable powder, water dispersible granule, granule and the like before sowing or planting and the like can be mentioned.

In the case of the paddy rice nursery box, the formulation may vary depending on the timing of, for example, application on sowing, application during greening, application during transplanting and the like. The formulations of dust, water dispersible granule, granule and the like can be employed. Application is also possible by incorporation into the grove soil, wherein the grove soil may be mixed with dust, water dispersible granule, granule and the like and, for example, incorporation into bed soil, incorporation into cover soil, incorporation into the entire grove soil and the like can be employed. Simply, a grove soil and various formulations may be applied in alternate layers.

As a method of application to a paddy field, a solid formulation such as jumbo, pack, granule, water dispersible granule and the like, a liquid formulation such as flowable, emulsion and the like are generally sprayed on a flooded paddy field. Alternatively, during rice planting, a suitable formulation can also be applied or injected to soil directly or after blending with a fertilizer. Moreover, by utilizing a liquid agent such as emulsion, flowable and the like to a water inlet and the flow source of water into paddy fields such as an irrigation apparatus and the like, a saving application along with the supply of water can also be performed.

For upland crops, treatment of seeds, a cultivation carrier to be placed near the plant body and the like during the period of from sowing to raising seedling is possible. For plants to be directly sown in the field, a direct treatment of seeds, a treatment of a plant foot of the plant under cultivation and the like are preferable. An application of granules, a soil injection treatment with a liquid agent with or without dilution with water and the like can be performed.
